I have a relative who lives in SF and I have to say, their tap water is unfuckingbelievably good. I've never tasted better water. In addition, it kinda makes sense to kill the bottled water craze in this country in particular - we have clean water sources and tap water is often far cleaner and better-regulated than a number of bottled waters (many brands often use tap water, anyways). We don't exactly have cholera epidemics here and frankly, the environment doesn't need more plastic bottles being produced anyways.
